Air-to-water Heat Pump
Appliance filled with flammable gas R32.
Before use the appliance, read the owner's manual first.
To realize the function of the air conditioner unit, a special refrigerant circulates in
the system. The used refrigerant is the fluoride R32, which is specially cleaned.The
refrigerant is flammable and inodorous. Furthermore, it can leads to explosion under
certain conditions. But the flammability of the refrigerant is very low. It can be ignited
only by fire.
Compared to common refrigerants, R32 is a nonpolluting refrigerant with no harm to
the ozonosphere. The influence upon the greenhouse effect is also lower. R32 has got
very good thermodynamic features which lead to a really high energy efficiency. The
units therefore need a less filling.
Before installation, please check if the adopted power is accordance with that listed on
nameplate, and check the safety of power.
The unit shall contact with the supply mains by a full disconnection device under
overvoltage category Ⅲ .
Before using, please check and confirm if wires and water pipes are connected
correctly to avoid water leakage, electric shock or fire etc.
Don't operate the unit with wet hand, and don't allow children to operate the unit.
The On/off in the instruction is for the operation to on and off button of PCB for users;
cut off power means to stop supplying power to the unit.
Don't directly expose the unit under the corrosive ambient with water or dampness.
Don't operate the unit without water in water tank .The air outlet/inlet of unit cannot be
blocked by other objects.
The water in unit and pipeline should be discharged if the unit is not in use, to prevent
the water tank, pipe line and water pump from frost-cracking.
Never press the button with sharp objects to protect manual controller. Never use
other wires instead of special communication line of the unit to protect control elements.
Never clean the manual controller with benzene, thinner or chemical cloth to avoid
fading of surface and failure of elements. Clean the unit with the cloth soaked in neutral
eradicator. Slightly clean the display screen and connecting parts to avoid fading.
The power cord must be separated with the communication line.
Any person who is involved with working on or breaking into a refrigerant circuit should
hold a current valid certificate from an industry-accredited assessment authority, which
authorises their competence to handle refrigerants safely in accordance with an industry
recognised assessment specification.
Servicing shall only be performed as recommended by the equipment manufacturer.
Maintenance and repair requiring the assistance of other skilled personnel shall be
carried out under the supervision of the person competent in the use of flammable
refrigerants.
